Discusses a study in which a group of high school vocational science students using behavioral objectives scored significantly better than did a control group on measures of terminal achievement, critical operations, residual achievement, and attitude toward instruction. (MLH)

A study of how science training of the teacher, type of school, and student age affects the science performance of children aged 5-11 showed that only student age significantly influenced student achievement. (MLH)

Compares the cognitive levels of groups of high school biology students, freshman physics students, and senior science students by testing them with two Piagetian tasks. Examines correlations between cognitive levels and other measures such as SAT scores. (MLH)

Examines regression analysis of 12 aptitude measures and an achievement criterion measure in a study of 285 ninth-grade science students who were randomly assigned to one of four individualized programs: teacher-directed treatment, media treatment, reading treatment, and programmed instruction treatment. (MLH)

College physics students' understanding of the process of science, as measured by the Science Process Inventory, was better for students in a traditional, structured laboratory than in an inquiry laboratory that covered the same experiments. (MLH)

Studies of a group of seventh-grade students who were tested for inquiry skills using the TAB Science Test showed no significant differences between those students who had studied the Intermediate Science Curriculum Study (ISCS) and those who studied another curriculum. (MLH)

Examines statistical correlations between six student traits and five measures of course success for 103 college students enrolled in an audio-tutorial introductory chemistry course. Among the conclusions was that the best predictors of success are the measures of prior achievement, notably grade-point average. (MLH)

Tenth-grade rural students of low verbal ability were taught a biology lesson using one of three instructional adjuncts: an advance organizer, behavioral objectives, or a set of adjunct questions. Achievement scores showed no significant differences among the treatment or control groups. (MLH)

No significant differences were found for grade level, sex, or instructional treatment (activity-based curriculum vs. textbook approach) for third and fourth grade science students as measured by Piagetian Classification Tasks, the Science Attitude Scale, and the Science Achievement Test. (MLH)

Reports the results of a factor-analytic study of the Meyer Test, which measures various aspects of science interests and of attitudes toward science. The populations involved were 380 tenth-grade high school Israeli students and 680 0-level students in England. (MLH)

Twenty-three high school biology students using the Biological Sciences Curriculum Study (BSCS) Blue Textbook were administered a weight conservation and two volume conservation tasks. A majority performed below formal-operational level, indicating that these students would be likely to encounter difficuluty with BSCS Blue Version materials. (MLH)

Administration of a modified Learning Environment Inventory (LEI) to 27 high school classes (science and nonscience) on three separate occasions indicated that student perception of classroom environment as measured by the LEI is consistent over time. (MLH)

Preservice elementary teachers who were taught science process skills in a series of hands-on laboratory activities scored significantly higher on a paper-and-pencil instrument on science process skills than did a control group. (MLH)

Discusses quasi-experimental and experimental research methodologies for investigating the relationships among teacher behavior, teacher competencies, student achievement, and student attitude outcomes. (MLH)

Describes a study in which one group of ninth-grade biology students read supplementary scientific journal articles rated at a grade level of 12.7; another group read the same articles rewritten to a level of 9.1. A major result was that the rewritten articles increased reading rate and comprehension. (MLH)
